The teaser is all of 10 seconds long, opening with Cate Blanchett as Lilith firing a gun, followed by Kevin Hart as Roland firing a gun, and then Jamie Lee Curtis as Tannis (who in a refreshing change of pace is not firing a gun), and then a quick flash of Ariana Greenblatt as Tiny Tina and Jack Black as Claptrap, although he’s not really identifiable as such.
